Iran will shift to a “fully offensive” military ​posture because efforts to negotiate a permanent end to the war with the U.S. have stalled, a senior Iranian official told Reuters on Monday, as Washington ruled out extending ‌a temporary ceasefire agreement.
Outward progress towards peace talks and a resumption of oil tanker traffic through the strategic Strait of Hormuz has ground to a halt, threatening to extend the conflict that the U.S. and Israel launched with attacks on Iran on February 28.


“Iranian entities must be prepared to escalate tensions in the Strait of Hormuz and wider region, as Iran will be ready to make decisions and take action on difficult decisions,” the Iranian official said, adding that Tehran would conduct a “timely and precise” military ​attack to break the U.S. naval blockade if diplomacy failed.
A memorandum of understanding signed in June to end the war had given Iran and the U.S. until Monday to reach a final ​peace agreement.
Signed on June 17, the memorandum set a 60-day time frame for a broader deal on Iran’s nuclear programme and U.S. sanctions.
The agreement, which declared ⁠the “immediate and permanent termination of military operations on all fronts,” quickly unravelled over a dispute about control of the Strait of Hormuz, the narrow waterway through which a fifth of global oil and liquefied ​natural gas flowed before the war.

BACK CHANNEL TO IRGC
In one glimmer of diplomacy, media reports said ​Trump had opened back-channel discussions with the Islamic Revolutionary Guard Corps, which has become more powerful during the war and controls large parts of Iran’s armed forces and the economy.
Axios, citing two sources with direct knowledge, reported that former Director of National Intelligence Tulsi Gabbard spoke with an Iraqi Kurdish leader with close ties to the IRGC, and that through this intermediary the U.S. delivered a message to IRGC commander General Ahmad Vahidi. Fox News later reported that Trump confirmed ​the report in a telephone interview.
The Trump administration was concerned whether Iranian negotiators across the table actually spoke for the IRGC, Axios said, at a time when Reuters was reporting that Vahidi had become a ​pivotal figure. Vahidi responded that he was aligned with the Iranian negotiators, Axios said.

“I can’t go into the details of it, but I will say that the conversations between the U.S. government and different areas of the Iranian government at ‌all areas ⁠is probably more robust than it’s maybe ever been,” Jared Kushner, Trump’s son-in-law and special envoy, said in a separate interview with Fox News Channel’s Chief Foreign Correspondent Trey Yingst on Monday.
